Abstract
According to one embodiment, a manufacturing method of a display device includes preparing a processing substrate by forming a lower electrode, forming a rib, and forming a partition including a lower portion and an upper portion, forming an organic layer on the lower electrode, forming an upper electrode on the organic layer, forming a first transparent layer on the upper electrode, and forming a second transparent layer on the first transparent layer. The first transparent layer and the second transparent layer are formed of organic materials different from each other. A refractive index of the second transparent layer is less than a refractive index of the first transparent layer.

A manufacturing method of a display device, comprising:
- preparing a processing substrate by forming a lower electrode above a substrate, forming a rib comprising an aperture overlapping the lower electrode, and forming a partition including a lower portion located on the rib and an upper portion located on the lower portion and protruding from a side surface of the lower portion;
- forming an organic layer on the lower electrode in the aperture;
- forming an upper electrode on the organic layer;
- forming a first transparent layer on the upper electrode;
- and
- forming a second transparent layer on the first transparent layer, wherein
- the first transparent layer and the second transparent layer are formed of organic materials different from each other, and
- a refractive index of the second transparent layer is less than a refractive index of the first transparent layer.
A display device comprising:
- a substrate;
- a lower electrode provided above the substrate;
- a rib formed of an inorganic insulating material and comprising an aperture overlapping the lower electrode;
- a partition comprising a lower portion provided on the rib and formed of a conductive material, and an upper portion provided on the lower portion and protruding from a side surface of the lower portion;
- an organic layer provided on the lower electrode in the aperture;
- an upper electrode which is provided on the organic layer and is in contact with the lower portion of the partition;
- a first transparent layer provided on the upper electrode;
- a second transparent layer provided on the first transparent layer;
- and
- a sealing layer which covers the second transparent layer and is in contact with the lower portion of the partition, wherein
- the first transparent layer and the second transparent layer are formed of organic materials different from each other, and
- a refractive index of the first transparent layer is greater than a refractive index of the second transparent layer.
